I have the FF3GP which I bought a few months ago. Great helmet for the price. Fits very similar to my Arai Signet and RX7... My only complaint about the lid is that I took the suggestion of Helmet Harbor and purchased a large based on my size with Arai. The helmet fits the same, but a little looser than my Arai's have. I remedied it by getting different cheek pads and now the fit is identical to the Arai, is lighter and plane looks good. I got the red,white & blue lid to stand out and represent my patriotism.
Great helmets at great prices and I will buy another one again before dropping $200 more on an Arai. Don't get me wrong, I love my Arai, but don't like their policies. Another side note, OGK is the direct competitor of Arai in the UK from what I've read.
